Disclosed are systems and methods which provide an interface for disparate software applications using an adapter associated with at least one application of a first type to interface the first application with multiple applications of a second type, each of which has an associated adapter. The new method described herein represents a significant improvement in transformation technology. The computer-implemented method may further include creating an event trail by identifying at least one event in the event history that led to the restricted event.
